The SEC's recent no-action letter for the DeFi project DoubleZero is being viewed as a significant positive development for the decentralized finance sector. Issued on September 29, the decision clarifies that tokens used to reward services such as storage and bandwidth do not qualify as securities. This precedent allows certain tokens to operate outside the scope of securities law, providing developers with the confidence to expand in the U.S. without regulatory concerns. This move represents a shift from previous enforcement actions and suggests a more open regulatory stance. The decision is expected to catalyze growth in DePIN projects, which reward real-world services, with projections indicating the sector could reach $3.5 trillion by 2028.
